` This invention relates in general to an auxiliary spring for vuse in association with the usual semi-elliptic chassis spring as comp'monly employed in motor vehicles and 'thel like, and relates in particularto the means of mounting and `retaining the vauxiliary spring in proper' relation to the chassis spring. f f

The inventionis `herebelow 'described iny one particular form as shown in the accom-v panying;dralwing inlwhich,

Fig. 1, is aside perspectiveview of my invention mounted on a vehicle frame in anv operative position; n Y

spring hanger. Y

Like characters 'of reference indicate like parts throughout the several views intheA drawing. n p

Referring first to Fig. 1 of the drawing,'a

lpair of semi-elliptic springs 10 and 11 are' secured to support a vehicleframe 9 in the usual and well known manner. A vehicle is ydesigned to carry a certain load'limit,but it is common practice to greatly overload the vehicle, much beyond the load yfor. which the springs were designed to carry, kand an aux-v iliary spring coming into action to care for the overload is desirable.

I form an auxiliary spring hanger, preferably of spring steel to have two vvertically positioned spaced-apart legs 13 and 14 and a bar 15 integrally interconnecting the top ends of the legs 13 and 14. The bar 15 is bent over to lie in horizontal plane normal to that of the legs. The legs 13 andv 14 and bar 15 arehere shown as formed from a single piece of material.

The auxiliary spring hanger is attached one to each side of the frame 9 by placing the legs 13 and14 against the outer sidesof 'n the frame side rails, substantially centrally of the chassis springs 10 and 11, with the bars 15 being uppermost and proj ecting` outwardly from the frame. A rbolt 16 Visslidingly passed through the lower end of each` leg v13 and 14 toextend inwardly under the framev 9 each to receive thereon an anchor bracket 17.

Each anchor bracket 17 has a foot 22 extending back under and along the bolt 16 toward the lower endk of the hanger foot, and also has an upper arm 2O extended back over and parallel' to the bolt.l6 to lieabove the Fig. `3, a top planl view ofthe auxiliaryv 'framerail leg 18 to carry a spring foot 19` r vwhichVNV turns sharply upwardly yfrom the outer end of'lthe'arm 20 to' incline slightly toward` the inner side of the frame,fsothat as the bracket 17 is slipped over `the bolt 16 andthenut 21 is drawn up on the bolt,` the.

vbracket-17 .will be carried-toward the frame f as indicated bythe dash lines in Fig'. 2.

In this position, the -auxiliaryhanger is securely attached'to the frame 9, without the necessity. of any holes having to be located and bored. The'lower bracket foot 22 pushes l outwardly on'the lower `end of the hanger foot'to tend to fulcrum the hanger' leg over the head of the rbolt 16 so as to-initially press the upper portion of the leg against the side of the frame, and the frame is actually reinforced by the combined action of the bracket y 17 and the legs 13 and 14 through the bolt 16.

Against the ,underside of yeach bar 15 are centrally positioned the auxiliarly semi-elliptic springs 24 and 26 and there secured by the .clips 25. The auxiliary springs are turnedwith their concave sides toward the main springs 10 and v11, andkeach auxiliary springv compressively engages the ymain springbelow it by ypressing through its free ends upon the blocks'27 which are secured by one end each under the leafclips 28 to the main springs. These blocks 27 serve not only to preventjwear on the top leaves of the main springs 10 and 11, but by spacing the free ends upfrom the main springs, aid in securing an initial no-load compression against the main springs. Y i v In addition to serving. as a relief under main spring overloads, the auxiliary springs 24 and26 mounted as here shown,also materially aid in checking the objectionable re'- free ends of the auxiliary springs compressively engaging againstthemain spring in the initial position. 1

While I have here shown andr described my invention in the form now bestgknown to me, it is obvious that its structure may be varied within the spirit of the invention, and' I thereforer donot desire to be limited'to ybound of themain springs by reason of the j this particular form, nor any more than may be necessitated by the following claims.

What I claim is:

1. The combination with airamesiderail of a spring hanger having` a vertically disposed leg adapted to Contact the outer side of the rail, a bolt passed through the lower end of the leg to lie under the side rail and a bracket carried on the inner end of the bolt, a lower foot extended back under the bolt toward said leg, and an upper Yt'oot adapted to elastically contact the inner side of the rail whereby said lower foot may contact the leg upon the yielding of said upper foot.

2. The combination with a frame side rail of a spring hanger having a horizontally disposed spring attaching bar and a plate verti- Gally disposed fromV the bar to contact the outer side o1 the rail and bracket clamping means yieldingly engaging said rail and said plate.

3. The combination with a iframe member of a spring hanger having a vertically disposed leg, a member horizontally extended -from the lower end of the leg on which the 'frame rests, and means associated with said horizontal member and the inner side of the frame member whereby the leg is rocked against the outer side oi' the frame member.

4. The combination with fa frame member of a spring hanger having a vertically disposed leg, a member horizontally extended from the lower end of the leO on which theirame rests and means associated withsaid horizontal member and the inner side ofthe frame member whereby the leg is rocked against the outer side of the frame member, said means causing the frame member to be yieldingly engaged against said leg.

ln testimony whereof I aiiiX my signature.
